Development consent criterion;2. Monitoring location is within Zone of Affectation, no EIS L A1,1min levels available;3. The noise emission limits identified in the above table apply under meteorological conditions of:- Wind speeds of up to 3 m/s at 10 metres above ground level; or- Temperature inversion conditions of up to 3ºC/100m, and wind speeds of up to 2 m/s at 10 metres aboveground level.4. Estimated or measured L A1,1min attributed to WCRS;5. NM denotes WCRS audible but not measurable, IA denotes inaudible;6. NA in exceedance column means atmospheric conditions outside conditions specified in development consent andso criterion is not applicable, or, there is no applicable criterion;7. Vertical temperature gradient (VTG) calculated using sigma theta values according to INP procedures; and8. Bold and red text indicates an exceedance of relevant criterion.11263_R01.docPage 16
